The guy hooked a little handheld computer up to it and tried. I never said anything about it to them, and I think he just expected he was going to be able to do it. When he asked what year mine is, I told him it's a '12, then he said they only have up to the 2010s in the handheld. I assume eventually they'll be able to. He also mentioned that some cars can just "learn" the new sensors. Tire Rack already told me I'd have to have it done at the dealership, and I did some research into it that pretty much revealed that the TPMS system that Honda and Toyota (and some other foreign cars) use pretty much has to be initialized by the dealer. I was hoping the i-MID would just let me disable the warnings, but NOOO.

I have an appt for Thursday. We'll see if I make it until then without putting duct tape over all the idiot lights.
The local dealership is doing it for me for $50, which is still ridiculous, but better than $100. My oil life is at 30% (with 8500 miles), so I need to get that changed, anyway.
They keep predicting more snow, but it hasn't snowed again since I put the new wheels/tires on, so I haven't really gotten to try them out yet. I will say the car already seems more stable with them on it. I think I'll look for new tires to replace the OEM Contis once spring rolls around. I looked at reviews of them, and they're pretty mixed. A lot of people really hate them.
